Phosphorescent Iridium Hydrazinonicotinic Acid (HYNIC) Complexes That Bind to Prostate Specific Membrane Antigen: Potential Photodynamic Therapy of Prostate Cancer

Chemistry – A European Journal, EarlyView.
A phosphorescent iridium(III) complex has been prepared with a 6‐hydrazinonicotinic acid (HYNIC) ligand tethered to a lysine‐ureido‐glutamatic acid pharmacophore, which binds to an enzyme, called prostate‐specific membrane antigen (PSMA), which is overexpressed in prostate cancer.

Phosphorescence of Heavy, T‐Shaped Pnictogen Trisamides in Solution at Room Temperature in the Near‐Infrared II Region

Chemistry – A European Journal, EarlyView.
The unique photophysical properties of heavy T‐shaped Sb and Bi trisamides are reported. A ligand‐to‐pnictogen charge‐transfer excitation from a redox‐active NNN pincer to a vacant pnictogen p‐orbital populates a triplet state that emits in the highly desirable NIR‐II region, with lifetimes up to the µs range.

Tailoring Electrostatic Attraction Interactions to Activate Persistent Room Temperature Phosphorescence from Doped Polyacrylonitrile Films

, 2021
Amorphous organic materials exhibiting room temperature phosphorescence (RTP) are good candidates for optoelectronic and biomedical applications. In this proof-of-concept work, we present a rational strategy to activate persistent RTP with a wide range ...

Synthesis and Functional Properties of Fluorinated Phosphonate‐Substituted Porphyrins: Excellent Photosensitizers and Robust Precursors for Photoactive Langmuir–Schaefer Films

Chemistry – A European Journal, EarlyView.
This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions

Chemistry – A European Journal, EarlyView.
Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, EarlyView.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.
